HATS-74Ab, HATS-75b, HATS-76b and HATS-77b: Four Transiting Giant Planets around K and M Dwarfs

A. Jordán, J. D. Hartman, D. Bayliss +32

The relative rarity of giant planets around low mass stars compared with solar-type stars is a key prediction from core accretion planet formation theory. In this paper we report o…

Scintillation-limited photometry with the 20-cm NGTS telescopes at Paranal Observatory

Sean M. O'Brien, Daniel Bayliss, James Osborn +17

Ground-based photometry of bright stars is expected to be limited by atmospheric scintillation, although in practice observations are often limited by other sources of systematic n…

The HD 137496 system: A dense, hot super-Mercury and a cold Jupiter

T. Azevedo Silva, O. D. S. Demangeon, S. C. C. Barros +28

Most of the currently known planets are small worlds with radii between that of the Earth and that of Neptune. The characterization of planets in this regime shows a large diversit…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…

NGTS clusters survey -- III: A low-mass eclipsing binary in the Blanco 1 open cluster spanning the fully convective boundary

Gareth D. Smith, Edward Gillen, Didier Queloz +27

We present the discovery and characterisation of an eclipsing binary identified by the Next Generation Transit Survey in the 115 Myr old Blanco 1 open cluster. NGTS J0002-29…

TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet

Ares Osborn, David J. Armstrong, Bryson Cale +125

We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…
